But they are also controlled by wind and lunar cycles not just objects
Yes, and the position and shape of continents
There are tides in the atmosphere, as well as in the water.
and in the land
your house rises about 11 inches every time the moon is overhead… the moons gravity has a huge effect on earth.
but
we can still affect the system, if we withdraw energy from it.
The idea that @berninghausen has put forward that the effects are tiny and can be ignored is old thinking. It works if the system is all linar effects, but if there are nonlinear effects ( ie chaos phenomena) you can not ignore anything, no matter how tiny, and that means you cant really predict at all. … we all know how difficult it is to predict weather… it is because tiny effects interfere.

Because of the terrain structure all around us, the forcast can be for rain but it never touches us. Only sure thing is the wind hence windfarms
I did some analyses of the position of the moon against rainfall. There is a small effect at our location. It is mainly the declination of the moon … the moons orbit wobbles north and south across the equator. When it is moving across the equator it tends to drag weather systems with it and bring major rainfall events. When it is at its extreme declinstion (south or north) nothing tends to happen.
The phase of the moon is less important , but it is true that major rainfall events do not tend to occur at a full moon, I think because the suns and moons gravity effects are opposed at full moon, so the gravity pull on the earth is reduced.
I must get back to that analysis… more to do… it is fun working with astronomical data.

The world is nonlinear. Trying to make it linear for our mathematical or administrative convenience is not usually a good idea even when feasible, and it is rarely feasible.
